Its main advantages are as follows:

① The specific strength of the plate is high.

② The core material is cheap and the consumption is large, and the surface material price is high and the consumption is small, so the production cost of this product is low.

③ Reasonable selection and collocation of surface and core materials can effectively meet the performance requirements of pre-designed plates.

For example, metal cladding is used to improve the fire resistance and water resistance of the board, and decorative board or plastic sheet is selected as the surface layer to improve the decorative effect.
